    Send an email to support with the table locations you want (ECM 9508 - ecm 9516) as well as a copy of a tune with the OS you want it added to.

I suspect some other module is coming in to play. the only way to make wot faster is to turn off stability completely or fool vss that car is moving faster. seem like c7 are not effect like ctsv or zl1

    The limit has to be within the ECM. I have a swap vehicle running only the ECM and TCM (2016 L83 and 6L80) and it does the exact same thing. WOT comes in at about 2300rpm or 5mph. I do not have these new tables yet, excited to see if it make a difference.

    So it could be a hysteresis on the throttle? Sounds like thats what this table controls.

    I uploaded the new beta today. The new settings were there, so I tried them. Very pleased with the results. Thanks for starting the thread Higgs Boson!

    after driving the car a bit now, there is definite change in off throttle feeling. I could see where some people may not like it or that its to much, I do enjoy my car with the tables adjusted all the way out. I am not able to tell a difference in "on throttle" I switched over to e85 at the same time and with the weather getting colder i do not get traction.

    Other than my truck feeling more responsive, I notice that the transmission is a little more aggressive when downshifting. I guess you could add a little to decel and correct this. One negative, if your foot is heavy, the fuel mileage will suffer some.

    I'll have to send in a request for my 2016 Silverado too.

    Kinda curious as to what it will feel like on a basically stock 5.3 with just the basic add on's and E85.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    You should just have to download the latest beta version and they should show up in your tune then.

    I downloaded the beta last night, they aren't there.

    Even used the navigator to manually type in one of the ECM tables listed in this thread, still nothing.

    Hmmm. Mines a 2015 and it worked so you may indeed need to email support.

    They emailed me back, they said they sent my file to an engineer to look at it. Haven't got an email back since Wednesday.

    I have a 2018 ZL1 and could not find these tables in my tune until I installed the newest Beta. Now they are there but the Torque Request Rate Limit is "disabled" in the stock tune. So I assume these tables are not used in my car and therefore no improvement to be seen in changing them?

    If you read the description, that is only while the vehicle is stationary.

    I ended up doing this last night on my 15 Silverado, min/maxing the tables. I'm not sure what to think about it yet, I do have a strange jump in the throttle now if I'm rolling about 1 mph and I quick tap the gas it jumps forward really quick. Seems like the limiters are for initial roll in of the torque.
